Utility model content
The purpose of this utility model to be constructed loaded down with trivial details problem to solve conventional prestressed stretch-draw component complex structure, propose a kind of novel pre-stressed stretch-draw component---prestressing force bar shaped steel carbon composite component, this component not only has to connect simply constructs simply from the feature of heavy and light, and has good service behaviour and higher safety stock.
The technical solution adopted in the utility model is: a kind of prestressing force bar shaped steel carbon composite component, comprise bar shaped steel arm-tie, bar shaped carbon fiber board, endpoint node and distribution bolt, described bar shaped steel arm-tie is high-strength hot-rolled steel strip, two-layerly to superpose up and down, be folded with bar shaped carbon fiber board between two-layer bar shaped steel arm-tie, described distribution bolt is two rows, spaced apart along bar shaped steel arm-tie length direction, and through being reserved in the bolt hole of bar shaped steel arm-tie both sides, fasten this laminated element; The length of described bar shaped carbon fiber board is identical with bar shaped steel arm-tie, and width is the distance that two rows distribute between bolt, avoids bar shaped carbon fiber board is bored a hole.
The two ends of described composite component are provided with the endpoint node ensureing bar shaped steel arm-tie and the co-ordination of bar shaped carbon fiber board.
As preferably, described endpoint node comprises anchoring otic placode, connects end plate, high-strength bolt and cementing agent, described bar shaped carbon fiber board is bonding with bar shaped steel arm-tie by cementing agent in end, described connection end plate is upper and lower two pieces, described composite component is clipped in the middle, and fixed by high-strength bolt, connect on end plate and be also welded with anchoring otic placode.
As preferably, described cementing agent adopts epoxide-resin glue, and between bar shaped steel arm-tie two ends and bar shaped carbon fiber board, steeping length is at least the epoxide-resin glue of 120mm.
The utility model bar shaped steel carbon composite component end, by two-layered steel plates therebetween one deck carbon fiber board, is connected by many M16 high-strength bolts, by two row M8 bolt connection reinforcement integral working beyond end.Carbon fiber board mechanics feature is high-modulus, high strength, and modulus of elasticity is better than steel, and tensile strength is the several times of steel.Carry out in reinforcement and strengthening process to steel work, respective advantage can be given full play to improve bearing capacity and the ductility of component.This patent adopts carbon fiber sheet, has high-strength efficient, corrosion-resistant, quick construction, the feature such as lightweight, it by after impregnated carbon fiber resin at mold curing and pultrusion continuously.
The reliable anchoring of the utility model endpoint node ensures carbon fiber board and the cooperative important prerequisite of high-strength steel arm-tie.
The utility model bar shaped steel arm-tie adopts the hardware of the energy tension of high strength.Described bar shaped steel arm-tie size, because length direction is much larger than thickness direction, therefore can be ignored by out of plane stiffness, be approximately flexible member.
The beneficial effects of the utility model: 1) this prestressing force bar shaped steel carbon composite component connected node simple structure, be easy to apply ripe bolt or solder technology, easy construction 2) this prestressing force bar shaped steel carbon composite component thickness is relatively little for overall structure span, before non-Shi Hanzhang, rigidity is more weak, in flexible state, pre existing stress technique and kinematics of mechanism mounting means can be utilized to realize without support installing, meet the trend of green construction; 3) relative to conventional Cable Structure, this prestressing force bar shaped steel carbon composite component does not need the parts such as ground tackle, cord clip, has larger to apply potentiality.4) carbon fiber board ultimate strength is high, is combined to form steel carbon composite component and have good service behaviour and higher safety stock with steel arm-tie, can ensure that structure normal work and not producing under limiting condition under applying working condition is collapsed suddenly.
